When your body suddenly feels off, it’s natural to feel alarmed. You might be debating whether to see an internist or a neurologist for a headache, often unsure which is the right choice. Here’s a guide to five common warning signs and the appropriate medical specialists to consult.
1. Sudden, Severe Headache with Dizziness
See a: Neurologist
A headache unlike any you’ve had before—especially one paired with dizziness—could signal a neurological emergency like a stroke or brain hemorrhage. A neurologist can quickly assess the situation with a brain MRI or CT scan. Don’t brush it off.
2. Chest Tightness and Difficulty Breathing
See a: Cardiologist or go to the ER
Tightness in your chest, especially if the discomfort radiates to your arm or jaw, could mean a heart attack or angina. If you’re short of breath or sweating, don’t wait—call 119 (or 911) and head to the ER immediately for an electrocardiogram (ECG).
3. Severe Abdominal Pain and Vomiting
See a: Internist or Gastroenterologist
For persistent abdominal pain and uncontrollable vomiting, consult an internist or gastroenterologist. While it could be simple indigestion, these symptoms might also indicate more serious conditions like appendicitis, gastritis, or even pancreatitis. Thus, an ultrasound or endoscopy can provide an accurate diagnosis.

4. Blurred Vision or Flashes of Light
See a: Ophthalmologist or Neurologist
These symptoms could indicate retinal issues, migraine auras, or neurological problems. It’s best to have your eyes examined by an optometrist first, and if they’re clear, follow up with a neurologist.
5. Numbness, Weakness, or Slurred Speech
See a: Neurologist or go to the ER
If one arm or leg suddenly goes numb or weak—especially if your speech becomes slurred—call for emergency help right away. These could be signs of a stroke or a transient ischemic attack (TIA). Even if symptoms vanish within minutes, urgent care is essential to prevent long-term damage.
Bonus Insight: Trembling Hands and Anxiety? Think Hormones First
Before attributing shaky hands or racing thoughts to anxiety or stress, consider a physical cause. An overactive thyroid (hyperthyroidism) can mimic anxiety and panic symptoms. A visit to an endocrinologist and a simple thyroid function test can uncover the true source. If your hormone levels are normal, a mental health check-in might be the next step.
Knowing when and whom to ask for help could prevent a serious health scare from becoming a crisis. If you’re unsure, start with a visit to a trusted internist or family doctor. They can assess your symptoms and refer you to the appropriate specialist. Regarding your health, being cautious is always the smarter call.
